After the hacktivist collective Anonymous released the alleged personal information of the GOP frontrunner Donald Trump Thursday, some people have been attempting to call the presidential candidate, but weren't getting very far. A call put in to the phone number provided by Anonymous initially let Mic leave a voicemail; a later call returned a recording saying the voicemail was full.

Anonymous released the businessman's alleged Social Security number and cellphone number, which has prompted social media users to call the Donald's phone. Other information about Trump was released, such as the names of his parents, children, legal representation and agent.

Anonymous declared "total war" on the Republican presidential candidate, calling on those with and without hacking experience to join the group.

"Dear Donald Trump, we have been watching you for a long time and what we see is deeply disturbing," a member of the hacktivist said in the video. "Your inconsistent and hateful campaign has not only shocked the United States of America, you have shocked the entire planet with your appalling actions and ideas."

He hasn't had much luck keeping his voicemails secret, either. Gawker reported that it received an anonymous email with an audio attachment of voicemails allegedly from liberal MSNBC hosts Tamron Hall, Joe Scarborough, Mika Brzezinski and Patriots quarterback Tom Brady.

In 2015, Donald Trump read off former presidential candidate Lindsey Graham's phone number in front of hundreds at a rally in South Carolina, according to CNN. The South Carolina senator appeared to take it in stride, asking his Twitter followers which phone should he switch to.
